As I understood, everything was over a long time ago, it is impossible to make money. only test.
You can certainly earn still, since its on testnet, the payments have to be sent manually for just a few more weeks.. distrobution is once per week (usually on Wednesday but sometimes is delayed until Thursday or Friday). The numbers in the description are factual, as distrobution is 4 eth + 100k vty is given out per week, how much that is split depends on the # of participants for the events and how many for each consensus answer correctly.
For anyone participating as a new user, there is a display bug for the ETH events that makes it not show on the UI fractions below .01ETH... so for example if you do an event and are rewarded .009 it will still show 0 until you go over .01 ETH... with that said there are no minimum thresholds for payments, you will be paid on distrobution no matter how big or small.
